Repro Steps & Context

After applying transitive pinning to the VS-Platform repo, I got this error:

error NU1107: Version conflict detected for Microsoft.CodeAnalysis.Common. Install/reference Microsoft.CodeAnalysis.Common 4.3.0-1.22228.4 directly to project Microsoft.VisualStudio.Extensibility.EditorHostService.UnitTests to resolve this issue.

This error gives irrelevant guidance, IMO. Adding a PackageReference to the conflicted package is no longer the appropriate step. Given we have CPVM with transitive pinning, the only fix is to add a PackageVersion item for the conflicted package to Directory.Packages.props.
